Narrated Abu Bakrah: The Messenger of Allah ﷺ said: Some of my people will alight on low-lying ground, which they will call al-Basrah, beside a river called Dajjal (the Tigris) over which there is a bridge. Its people will be numerous and it will be one of the capital cities of immigrants (or one of the capital cities of Muslims, according to the version of Ibn Yahya who reported from Abu Mamar). At the end of time the descendants of Qantura' will come with broad faces and small eyes and alight on the bank of the river. The town's inhabitants will then separate into three sections, one of which will follow cattle and (live in) the desert and perish, another of which will seek security for themselves and perish, but a third will put their children behind their backs and fight the invaders, and they will be the martyrs.

Narrated Anas ibn Malik: The Prophet ﷺ said: The people will establish cities, Anas, and one of them will be called al-Basrah or al-Busayrah. If you should pass by it or enter it, avoid its salt-marshes, its Kall, its market, and the gate of its commanders, and keep to its environs, for the earth will swallow some people up, pelting rain will fall and earthquakes will take place in it, and there will be people who will spend the night in it and become apes and swine in the morning.

Salih ibn Dirham said: We went on the pilgrimage and met a man who asked us: Is there a town near you called al-Ubullah? We said: Yes. He said: Is there any of you who will undertake to pray two or four rak'ahs on my behalf in the mosque of al-Ashshar, stating "they are on behalf of Abu Hurairah"? He (Abu Hurairah) said: I heard my friend Abul Qasim ﷺ say: On the Day of Resurrection Allah will raise martyrs from the mosque of al-Ashshar, who will be the only ones to rise with the martyrs of Badr. Abu Dawud said: This mosque is near the river.
